So, from a quick read, I think there are a few things at play here that allow for "compression of random data".

One, and probably the biggest one, _this isn't lossless compression_. As other commenters mentioned, this aggregates groups of points into line segments and stores their slopes (allowing for a pre-specified error of up to epsilon).

Two, while the sample input data is randomly generated, it then needs to be sorted before it can be used here. This completely changes the distributional qualities (see: order statistics sampled from a uniform distribution [0]). Just as a toy example, suppose this was a million randomly-generated binary digits. Sure, you could store the million digits in sorted order, or you could just use run-length encoding and say "I have 499,968 zeroes and 500,032 ones" [1].

[1] I know, this is a dense sampling on the input space. But that's the sort of intuition that allows you to compress sorted data better than you'd be able to compress the unsorted data. The provided C++ code provides a sparse sampling.

I don't know why it looks like you're being downvoted. Your comment adds to the conversation, and is correct.

The students who have the hardest time with this sort of controlling family are the ones who have family that are wealthy and well-connected. That's not saying there aren't low-income folks with these problems; they just don't know how to navigate the systems.
> So the engine shut-offs for the SN8 test were indeed deliberate.

Yes. As you burn the fuel, the ship gets lighter and you need fewer engines. The big surprise was the engine-rich exhaust during the landing burn.
You're looking at it wrong.

The supply is rapidly increasing. it doesn't matter that they move. Eventually there will be competition for jobs and prices will go down - because virtual work means the entire world is a job market.

The first airplanes had a clear commercial advantage over other methods of transport: speed.

High-value, low-mass packages were transported by airplanes by 1911; by 1918 the USPS had an official air-mail service. That's fifteen years from the Wright Brothers' flight, and only ten years after the first flight of a full mile's distance.

So airplanes were economically a net positive 15 years after their invention. Chaum's ecash, which I think is reasonably comparable to the Kitty Hawk flight, was 25 years ago.

The primary use of Bitcoin that I encounter in my daily life is in ransom requests. If I want to make a legal million dollar payment, it's easier and safer to have the bank do it than to use cryptocoins. If I want to make a $20 payment, it's much easier and safer to use a credit card than cryptocoins. While I quote these extremes, everything [legal] in between is also easier and safer than cryptocurrency.

If the "things that need to be worked on before" don't include any of these cases, what do they include?
It's amazing how far the world has advanced in just 29 years!
Perhaps a good life can be defined in terms of a lack of distraction. That does not mean we should value activities from 1000 years ago more. For some it may mean quite the opposite since they are no longer distracted by the struggle to fulfill basic needs so pursuing the benefits of modernity is possible. For others, it may mean ignoring the distractions of modernity while seeking the purity of the past.

The problem with the current trajectory of technology is that it seeks to strip us of autonomy. We are usually presented with means of consumption, rather than courses of action. I suspect that is what people mean when they discuss distraction.

> (I usually suggest that displays being connected over Thunderbolt not be combined on the same chain as storage devices to improve the reliability of your mounted volumes.)

This is how you get cargo cults... Thunderbolt isn't a "lossy" channel; the real concern is ultimately what bandwidths you need. The most difficult factor in this is determining whether your storage is write-heavy, read-heavy or both. (If it's a SSD, that is - HDDs don't even get remotely near TB bandwidths.)

The general rules are:

- Displays: output bandwidth, and quite a lot of that
- eGFX: mostly output (textures) + a reasonable amount of input
- 10G/40G NICs: generally input bandwidth, somewhat use case dependent
- Storage: no general rule, strongly use case dependent

Also, the PCIe TB<>CPU connection needs to be considered, particularly in some older laptops it's only a PCIe 3.0×2 link, which caps out at 16GT/s.

If anything, it'd be nice to get good per-device bandwidth counters somewhere; not sure if the PCIe bridges can provide that data somehow (through QoS/AER features maybe?)

Why doesn't Google agree to MBC, omit participants from search results?
Australian lawmakers are trying to push through a Media Bargaining Code that makes Google to pay for the right to display the link, snippet, and image of media companies' content (news articles) in search results.

I agree that it would [heavily affect the way search works](https://www.youtube.com/watch?v=dHypeuHePEI)

So, why wouldn't Google just agree to the code and simply not show the participating media companies' articles in search results?

From my cursory analysis, this would

i) Give (much) more traffic to smaller media companies who don't sign up to the code
ii) Cause participating media companies to rethink after they lose traffic

Why doesn't Google give up the fight and take this approach?

Also, is there any platform where Google *does* do more than simply display the title of article, an image, and snippet? (if so, I would be more sympathetic to the Media companies pushing for the code, since Google could then be collecting ad revenue by essentially scraping and displaying others' content)

Note that I am not against using python in mission-critical code.

I was referring to untestable code with a myriad of edge-cases, in which case you have a problem that will surface sooner or later, be it 2to3 transition or something else.

If the code is truly static, you can ignore the transition and deprecation. Otherwise you should probably work on documentation/testing/refactoring and/or porting to another language.

2to3 transition was handled badly, up to about 2.7 and 3.4 or so, but the pains described here seem mostly self-inflicted, and I don't see it as an argument against the needed changes.
Swiss person here. Over the last 2 weeks, dozens of my contacts (often total non-techies) have installed Threema and/or Signal. I've heard of a lot of family chatgroups moving away from WhatsApp.

WhatsApp has near-total market penetration in Switzerland. I hope this will change now, at least a bit. Until recently, you'd get strange looks if you mentioned that you don't use WhatsApp. (People sometimes assume that means you don't own a smartphone.)

As a donor I feel that organizations should provide some details how donations are used. I'm requesting the same from other organizations I'm donating to if those organizations are more than just three persons working on a free software project in their spare time.

Originally donations to matrix.org foundation were supposed to be used to fund matrix protocol work and to hire a developer. This is still listed as a goal (that was reached) on Patreon.
Only due to asking I found out that this never happened and donations are used to pay matrix.org homeserver instead, which of course is also a good cause, but should be communicated transparently.

I don't mind the accounts specifically, I just think that making them public is the easiest way to fulfill the needs of transparency. Of course a summary on the website, a blog post with explanations, etc, would also be nice, but I understand those mean extra work and there might be more important things the prioritize.

Hi Jouni!

You may find interesting these other papers of ours:

- The ALENEX21 paper "A 'learned' approach to quicken and compress rank/select dictionaries" (http://pages.di.unipi.it/vinciguerra/publication/learned-ran..., https://github.com/gvinciguerra/la_vector), where we introduce a compressed bitvector supporting efficient rank and select queries, which is competitive with several well-established implementations of succinct data structures.

- The ICML20 paper "Why are learned indexes so effective?" (http://pages.di.unipi.it/vinciguerra/publication/learned-ind...) where we prove that, under some general assumptions on the input data, the space of the PGM-index is actually O(n/B^2) whp (versus Θ(n/B) of classic B-trees).

A few anecdotal observations:

- That people can't tell the difference between a $22 bottle and a $119 bottle does not surprise me; I've long suspected wines in the $100 - $n000+ range were priced arbitrarily or down to esoteric factors.

- Is $22 considered "cheap"? e.g. I would imagine the majority of people may be able to easily tell the difference between a $119 bottle and a $5 bottle.

- I would not say expensive wine tastes "better" but rather that it tastes "specific". Some may prefer the taste of cheaper wines, but most would prefer the expensive taste. Take for example a Lambrusco: it's an inherently "cheap" wine type, despite being DOC, largely due to being young and made from high-yield grapes. But it also has a very specific flavour that would never be associated with expensive wines. But it's not "worse"; it has it's place and people much prefer Lambrusco in certain contexts.

> boarding a plane while being infected is a sure way to spread COVID to people who will be in contact with even more people wherever they land.

The actual airplane is not seen as a high-risk place for spread of COVID due to the air circulation. It is more likely for people to spread the disease while waiting in the queues in the airports on either side.
> Boeing is too important to go out of business.

I hear this a lot and I get it, but I'm not so sure it's true. If Boeing dies, their assets don't just evaporate with them. There are half a dozen companies in the US who could take over where they left off - hopefully with better leadership this time around.
These sort of naturalist arguments seem to make little sense when thought about more clearly.

Of course that:

a) Destroying the environment is probably more destabilizing than keeping it intact... that's almost always the case with conservation vs change, conservation is the safe move

b) Destroying all insects (i.e a whopping 2/5th of all multi-celular bio diversity) would result in catastrophic damage... destroying 2/5th of all biodiversity would result in catastrophic damage.

The onus on any given insect conservation advocate is to prove:

1. Insects are more critical to the environment than other things we put more money and time into preserving (e.g Australia should spend more on preserving black widows and less on preserving koalas)

2. A very specific insect is critical and thus should be preserved at all cost, even if it means putting more money into the nature-preservation system

3. The bio-diversity of insects as a whole is dropping at an alarming rate compared to other species and this is harmful and unprecedented (biodiversity boom and bust cycles are the norm, usually)

I'm not saying the above 3 points can't be made.

But this article doesn't make them.

It sounds just like someone signaling "Hey, I'm a hippie ecologist, I love nature, even insects that sting, I'm that much of a group member, love me" rather than providing any new information or concrete policy proposal or even a meta-level argument for getting new information or creating new policy proposals.

The general idea of "we shouldn't destroy" nature has been around since, I assume, at least 5000 years ago or so, when bronze-age humans burnt down most forests in Europe and then realized this was bad and proceeded to replant and protect, or even venerate, forested areas. It's old new, nobody disagrees we should protect nature, it's just a typical tragedy of the commons problem, and one that hasn't been handled that badly thus far.
Saying that this particular "thing" is the wrong thing is not the same as saying nothing should be done. Every solution has both a benefit and a cost. The balance of those two is part of deciding whether a given solution is reasonable or not. The fact that something should be done does not mean that every "something" is a reasonable thing to do.

What Ever Happened to ICQ? (2019)
"ICQ, short for the phrase “I Seek You,” laid the groundwork for standalone instant messaging clients when it arrived in November 1996. Think about how long ago that was...

Microsoft’s trailblazing Windows 95 was barely a year old, Nintendo had just introduced the N64, and those with a reason to have a cell phone actually used it to talk on.

Launched after less than two months of development from Israeli company Mirabilis, it predated and influenced many of the popular chat programs of the era including AOL Instant Messenger, Yahoo! Messenger and MSN Messenger."

For many years, backpackers from Eastern Europe have made fake yellow-fever vaccination certificates so that they could cross African countries’ borders. It is not that they wanted to avoid the vaccine, it is just that this vaccine was very difficult to obtain in Eastern Europe, with only a handful of shots made available each year. Public health authorities around the world knew that some percentage of yellow-fever vaccine certificates would be fake, but this was not seen to threaten the overall effectiveness of vaccine requirements. I don’t see why the same can’t hold for COVID.
That depends on whether you consider Math something we discover or something we invent. If it is something we discover, universal truths, then Math is a science, uncovering truths in the same way physicists and chemists and others do. If it is something we invent, then perhaps it is engineering or art?

This is one of the great debates of the philosophy of mathematics. Surely the arbitrary symbols we use to represent mathematical concepts are "invented". But Math is much more than the symbols.

If we encounter aliens would they have the same mathematical concepts, or would theirs be completely different? Studies looking for basic numerical concepts in animals have shown that some animals really can grasp the basics the same way humans do. Is that due to human bias? Common DNA, or universal truths?

When announcing the delay in the implementation of their new TOS, WhatsApp wrote: “We want to be clear that the policy update does not affect the privacy of your messages with friends or family in any way”.

Note the careful wording regarding “the privacy of your messages with friends or family”:

- This excludes the privacy of messages with third parties (WA business)

- This excludes your privacy as a person (your communication behavior and all metadata)
The state can, arguably, address the problem more systemically than a city focussed on the local aspects.

Whether or not it will actually achieve that...? I don't know. And not for "government is incompetent" reasons, but because it's a hard problem with root causes that are difficult to address.
funny that you bring up contabo. i have been thinking about setting up a selfhosted email instance and that could lead to more stuff later on but bandwidth is like night and day.
on contabo cheapest vps is like €4.99 / month, 4 vCPU Cores,8 GB RAM, 200 GB SSD, 200 Mbit/s Port, 1 Snapshot and "32 TB of transfer is already included in each VPS package."

while on vultr.com, the ipv4 cheapest is like 25 GB SSD, 1 CPU, 1024 MB RAM, 1 TB transfers for $5/mo.

that is such a huge difference that i dont know what is real.

i want like 10TB storage vps from contabo but apparently they dont have it. do you know anyone like them? i have looked at scalaway and others but they dont say pricing of bandwidth past the allowance. like only for their s3 they say pricing which is exorbitant like the ones mentioned in the article

edit:
vultr object storage says "$0.01 per additional GB transferred "
https://www.vultr.com/products/object-storage/

and scaleway says
Inter-regional* and external outgoing data transfer to other products from a different region and the Internet: 75 GB free every month, then €0.01/GB

same pricing for backblaze b2 for downloads

yes, well in Germany, the Federal Minister of Health said that "Vaccine won't be mandatory" but there were already some decisions to fire/punish employees (i.e Nurses and Soldiers) that refused to take the vaccine.

It's not so much the syntax as that I have never once thought that I wanted an imperative stateful language with variables and loops (!) for applying styles to the DOM, instead of a declarative one. And it seems like a disastrous idea to me.

And I haven't been thinking this for 20 years or something set in my ways, I was previously only vaguely aware of this "controversy". In fact, while you suggest the unfamiliarity or dislike of Lisp syntax is behind opposition, I think it's probably the reverse, most of the people (especially in 2020) pining over DSSSL are specifically those in love with Lisp who were hoping it would make it an again mainstream technology -- I'm going to reverse it and say your advocacy is less about the idea of using a full programming language for HTML styling and more about just liking Lisp and wanting an application for it.

But also, sure, syntax matters for technology accessibility. It is arguably inappropriate to require someone to "learn Lisp" in order to style HTML.
